SPEC 44 features a dual-wall construction that blends the excellent mechanical and chemical properties of radiation-crosslinked polyvinylidene fluoride (PVDF) and outstanding physical and electrical characteristics of radiation-crosslinked polyalkene. The insulation system features copper conductors (tin, silver, nickel or aluminum coated) beneath primary insulation of radiation-crosslinked, extruded polyalkene and topped with a Radiation-crosslinked, modified PVDF jacket.
This high-performance cable includes many features such as: being lightweight and small in size, resistive to electrical arc tracking and most chemicals, low smoke and low corrosive gas generation and voltage sizes 2500, 1000 and 600. A modern dimensional replacement for glass/PVC/nylon braid type wire and cables can be offered in airframe constructions for SPEC 44. This wire SPEC 44 crosses directly with Allied’s MIL-W-M81044.
